Bests & Worsts Reviews from Amazon

I have amazing results - like truly brand-new looking headlights on a 14 year old BMW X3 w/six-figure mileage. However, that wasn't the case the first time around. Follow my advice - not just the instructions - and you will get the results you want. My first time around I followed the instructions to the letter. I was amazed at the oxidation that came off in step 1, and even made sure to use all four wipes even though they were clear by 3, because the instructions said so. Step 2 I kept running water trickling across the headlight the whole time, and spent a timed 4 minutes on each headlight at each grit. After applying step 3 I thought I had done an amazing job. Then it dried overnight. And it was hazy. You could see the horizontal sanding lines if you looked closely. It was way better than when I started, but nowhere near looking "like new". Probably about 75-80% there. So I called the company and asked for warranty help. I got a voice mail and thought for sure I'd never hear back (I couldn't find an email address or online form to complete). Sure enough, my phone rang about five hours later and a nice guy listened patiently, took my information, and said they'd overnight a new set of steps 2 and 3: sanding pads at both levels, and the ceramic coating. I asked if it would be a problem for me to spend more time, and even do my own polishing after their time limit and direction. He said to go for it. That was the trick. So, I did it again today. Skipping step 1, I started with the 2000 grit paper. Instead of trickling water, I sprayed the headlights after each maybe 30 seconds of sanding, and it was in the shade. I spent a solid 5 minutes at 2000 grit. Then I spent about 8 minutes using 3000 grit on each. This was important, as I found it was important to spend longer at the higher grit to really soften the surface. I had a very consistent and smooth-ish surface, but could still see sanding lines. I pulled out a bottle of clear plastic polish (maguiar's #10). I used to use this stuff on a soft plastic convertible window maybe 15 years ago, but never threw away the bottle. I spent about five minutes on each headlight with this polish. I didn't use anything really abrasive - just a cotton buffing rag, and some elbow grease. After this step, the headlights were looking 95% even before the ceramic coating. Then came step 3. It was again like magic. But this time, it stayed like magic. So, why 4 stars instead of 5 when this stuff works? Because it doesn't work as well as it should with their instructions. You need to get it polished just a bit more to really get amazing results. Now I'm thrilled. It dried a couple hours, and then rain came I was worried, but it still looks awesome. I'll update this review if something changes, but I'm a believer - with the right modifications! I have included three pictures of the driver side headlight to show you the differences. The picture from a little further away where the headlight is cloudy is before I did anything other than clean it. The picture a little closer where it looks pretty decent but not glass-like is after the first series of following the instructions. And finally the close-up where it looks like glass is after doing step two and step two plus my clear plastic polish, and then step three a final time. And that how it truly looks. Like glass. Love the result.
